Bearing Reactions for continuous span

I am designing a simple made continuous bridge with PGSuper 2.7.2.1. I'm wondering why it cannot give out the bearing reactions of interior piers?

It is expected that PGSuper can calculate the most adverse loading condition and corresponding reactions for substructure design.

You are right, bearing

You are right, bearing reactions are not reported at continuous piers because, once the system is continuous, there is only one bearing. Total pier reactions are reported for the location.

The one thing that is missing is bearing reactions for loads prior to continuity. This may be added in a future version.

Thanks for response. 'once

Thanks for response.
'once the system is continuous, there is only one bearing.', why?
In general, we don't replace bearings after continuity, but let them remain in position, which means that there will be 2 rows of permanent bearings, not only one. So the bearing reactions need to be reported.
